4 Claims.

This invention relates to sash holders, and the object of the inventionis to devise a simple and effective sash holder which will normally holdthe sash in a raised position but will permit the sash to be lowered bythe application of downward pressure.

Counterbalancing weights supported by cords running over rollers arecommonly used to retain window sashes in raised position, but these areexpensive and are not readily applied to window frames not speciallyconstructed for the purpose. Numerous sash holders have been devisedwith the object of devising something cheaper and more convenient andsomething which may be applied to the sash or frame without difficulty.Previously known constructions have been complicated, expensive,unsightly or ineffective, having no positive means of placing the rollerin a wedging position whereas the roller in my invention moves intowedging position by the positive action of gravity.

Other types also use a small pin or axle running in very thin narrowjournals which will soon either break off or wear out completely. Myinvention eliminates these objectionable features which enable it to beused indefinitely without signs of wear, and is simple, inexpensive,unobjectionable in appearance, and readily applied to any window.

According to this invention a roller is mounted in a vertical channeland is adapted to roll in engagement with a sash between said sash and adownwardly and outwardly extending depressible wedging member in thechannel, said member being bent intermediate its ends and fulcrumed onthe bottom of the channel whereby when thee sash is moved upwardly theroller will roll freely, and when it is moved downwardly the roller willbe wedged between the sash and the depressible member.

The invention is hereinafter more particularly described and isillustrated in the annexed drawing in which Fig. 1 is a front elevationof part of a window and window frame showing the sash holder appliedthereto;

Fig. 2 a vertical cross section on the line 2-2 in Fig. 1, with the sideof the casing of the sash holder broken away;

Fig. 3 a horizontal cross section of the sash and frame on the line 3-3of Fig. 2;

Fig. 4 an enlarged vertical section of the sash holder showing theposition of the roller in full lines when the window is pulled down, andin dotted lines in the holding position;

Fig. 5 an enlarged vertical section of a modified form of sash holder;and

Fig. 6 a vertical section of a further modification of the sash holder.

In the drawing corresponding numerals in the 5 different figures referto corresponding parts.

The sash holder comprises a rectangular metal casing I open at one sideand having brackets 2 extending from the ends thereof adjacent one ofthe sides, said brackets having apertures therein 10 adapted to receivea screw or nail for securing the sash holder to a window frame 3. Thesash holder is mounted on the side of the frame near the top of the sash4 with its open side facing the sash, but sufiiciently spaced therefromto per- 5 mit free movement of the sash up and down relative to theframe and the sash holder.

A flat metal leaf 5 of substantially the width of the channel formed bythe casing I of the sash holder, and of substantially the same length ofsaid channel is mounted therein by means of a bolt 6 which passesthrough one of the sides of the casing l. Mounted on the bolt 5 is acoil spring I which is held thereon by means of a nut 8. The sides ofthe nut bear against the sides of the casing i so that it will notrotate, and the compression of the spring may be varied by turning thescrew 6 which passes freely through the hole in the casing l and througha hole in the end of the leaf 5.

The leaf 5 is bent at a point between its ends but adjacent to the endthereof through which the bolt 6 passes, and said leaf is adapted torock or pivot on the line of bend, the bottom of the channel againstwhich the leaf bears acting 2.535 a fulcrum and there being sufficientplay or looseness between the bolt and the hole in the leaf to permitthe rocking movement of theleaf relative to the bolt. The end of theleaf through which the bolt 6 passes normally lies flat against the sideof the casing l, thatis to say against the bottom of the channel formedby said casing, whereas the other end extends outwardly at an angle fromthe bottom of the channel.

A roller 9 which is substantially the length of 5 the width of thecasing is adapted to roll up and down in the casing in engagement withthe leaf 5. The roller is of such size that when it is in the end of thecasing adjacent the nut 6, which is the upper end of the casing when thesash holder is mounted on a window frame, the roller is held entirelywithin the casing and will roll freely therein, as, for instance, if thesash 4 is raised. If, however, the sash drops or is pulled down theroller will be wedged between the sash and the sloping part of the leaf5 and will stop the further downward movement of the sash by pressingthe sash into frictional engagement with the frame. The bolt 6 may beturned so as to adjust the pressure of the spring 1 sufficiently thatthe leaf 5 will not pivot or will pivot only slightly under the wedgingaction of the roller induced by the downward movement of the sash causedby gravity. If, however, additional downward pressure is applied, as forinstance the pressure of the hand of a person who wishes to close thewindow, the wedging action on the roller will cause the leaf 5 to rockor pivot on the line where it is bent, that is on the line of junctionbetween the part which normally lies flat against the bottom of thechannel and the part which normally extends outwardly at an angle fromthe bottom of the channel, against the pressure of the spring l7, untilthe roller and leaf adopt the position illustrated in full lines in Fig.4, with the short part normally vertical and extending outwardly at anangle from the bottom of the channel and the longer normally diagonalend part compressed into a position substantially parallel with thebottom of the channel, thus substantially eliminating the wedging effectand permitting the roller to rotate only subject to the friction causedby the pressure of the spring, which however is not sufiicient toprevent the window from being pulled down, since the spring pressure hasbeen so arranged and adjusted. It will be observed that the bottom ofthe channel acts as a fulcrum on which the leaf rocks.

If desired the sash holder may be morticed in the frame so that it willbear against the edge of the sash, as illustrated in Fig. 5. In thiscase the brackets 2' correspond to the brackets 2 in the other figures,but they extend from the ends of the casing l at the front thereof so asto secure the casing in the mortice or groove formed therefor in theframe. Likewise in this modification the head of the screw 6 is insidethe casing in the position where the nut is shown in the other views,and the nut is located behind the casing in the position in which thehead of the screw is shown in the other views, although preferably thebolt 6 will be screwed into a threaded hole in the bottom wall of thecasing itself. The sash holder will be located so that the upper endthereof will extend above the top of the sash when the sash is in itslowermost position, so that the bolt 6 may readily be turned by means ofa screw driver to adjust the tension of the spring without removing thesash.

A further modification of the sash holder of the type which may bemorticed in the frame is shown in Fig. 6. It will be noted that the coilspring I as shown in Figs. 1-5 is omitted in this construction. The leaf5 is bent at a point between its ends, said point being practicallyadjacent to the end of the leaf through which the bolt 6 passes. The"head of said bolt 5 engages directly the surface of the short end ofthe leaf 5 wherein the leaf per se acts as a spring fulcruming along theline of junction between the two bent portions of the leaf and havingthe same action on the roller 9 when the sash is raised and lowered ashereinbefore mentioned. The tension of the leaf when acting as a springmay be increased or decreased by merely adjusting the bolt 5. A furthervariation in this type of sash holder is the stop 9 which is an upwardprojection of the lower bracket 2, such stop preventing the leaf 5 fromengaging the sash when the leaf is under high tension.

What I claim as my invention is:

1. In a sash holder, the combination of a roller; an open sided casingforming a channel in which the roller is adapted to roll in engagementwith a sash; a. flat leaf in the channel behind the roller, bentintermediate its ends, one end part thereof normally lying flat againstthe bottom of the channel and having a hole therein and the other endpart thereof extending outwardly from-the bottom of the channel, theline of junction between the two parts engaging the bottom of thechannel which acts as a fulcrum on which the leaf is adapted to rock; apin carried by the casing, provided with an abutment and extendingthrough the hole, there being sufiicient play between the pin and thehole to permit rocking of the leaf and a coil spring mounted on the pinand bearing against the leaf and abutment.

2. In a sash holder, the combination of a roller; an open sided casingforming a channel in which the roller is adapted to roll in engagementwith a sash; a flat leaf in thechannel behind the roller, I

bent intermediate its ends, one end part thereof normally lying fiatagainst the bottom of the channel and having a hole therein and theother end part thereof extending outwardly from the bottom of thechannel, the line of junction between the two parts engaging the bottomof the channel which acts as a fulcrum on which the leaf is adapted torock; a pin carried by the casing and extending through the hole in theleaf, there being sufficient play between the pinand the hole to permitrocking of the leaf, a coil spring mounted on the pin and bearingagainstthe leaf; and means for adjusting the tension of the spring.
